Question

There are three hydrogen atoms and a nitrogen atom in a molecule of ammonia. Mention the formula of ammonia and determine the valency of the nitrogen atom in it?
​

Answer 1

Answer:

Ammonia which is NH 3 _3 3 , One atom of nitrogen combines with 3 atoms of hydrogen. The valency of nitrogen is 3 because it needs 3 atoms of hydrogen to form ammonia. Magnesium has valency equal to 2 + ^+ + because the electronic configuration of Mg is [2,8,2].

Answer 2

Answer:

Ammonia which is NH_3 , One atom of nitrogen combines with 3 atoms of hydrogen. The valency of nitrogen is 3 because it needs 3 atoms of hydrogen to form ammonia.
